Texas Republican Rep. Steve Stockman threatened Monday afternoon that he would file articles of impeachment against President Barack Obama if he institutes gun control measures with an executive order.

“I will seek to thwart this action by any means necessary, including but not limited to eliminating funding for implementation, defunding the White House, and even filing articles of impeachment,” Stockman said in a statement.

At his press conference Monday, Obama floated the possibility of using executive action to enact policies aimed at reducing gun violence.

“Any proposal to abuse executive power and infringe upon gun rights must be repelled with the stiffest legislative force possible,” he added. “Under no circumstances whatsoever may the government take any action that disarms any peaceable person — much less without due process through an executive declaration without a vote of Congress or a ruling of a court.”

He concluded by claiming that an executive order would be not just “not just an attack on the Constitution,” but also an “attack on Americans.”

“If the president is allowed to suspend constitutional rights on his own personal whims, our free republic has effectively ceased to exist,” he said.
